the combustion and air chamber respective-v ly. Each shield is preferably supported by a rod 22, and at the front of each wall 1 and .3 I have provided suitable members 23 and chambers.

It will thus be seen that Ihave provided a portable camp stove so designedv that the fuel may be quickly, evenly and accurately placed over the fuel rate, and which is so construct-- ed that such uel grate may be moved toward or from the cooking grate at any time during the operation of the stove. In this manner'a correct fire may be obtained at all times, corresponding to t e article or object to be subjected to heat. If a charcoal or coke fire is used it will be obvious that a minimum amount of fuel will be required and that such glowing bed of fuel may be raised or lowered,

as the'case' requires. It will also be obvious that this mechanism for raising the fuel grate may be applied similarly to the cooking grate, to raise or lower the same.

It will furthermore be obvious that by providing damper shields for the front of the combustion and air chambers that I have made it possible to accurately control the introduction of air into the fuel bed at all times,

as the matter of adjustably supporting the damper shields permits of a large number of relative arrangements.

What I claim is:

1. A camp stove, comprising side walls and a rear wall, a cook-ing grate forming the top of said stove and hinged at one end to permit raising thereof, a fuel grate positioned below the cooking grate. permanently positioned movable means for supporting said fuel grate and means positioned exteriorly of one wall of said stove and directly connected to said movable means, whereby operation of said means will raise or lower said fuel grate relative to the cooking grate.

2. A camp stove, comprising side walls, a fuel grate positioned between said walls and defining a combustion chamber and an air chamber. and damper'shields pivotally and adjustably supported at the front of said stove and at'the front of said combustion chamber and air chamber.

chamber and air chamber.

5. A camp stove, comzprising side walls, a

vertically adjustable fuel ate positioned between said walls and de ning a combustion chamber and an air chamber, and damper shields pivotally and adjustabl supported for vertical adjustment at the rent of said stove and at the front of'said combustion chamber and air chamber, the shield for said combustion chamber being of less height than the air chamber shield.

6. A camp stove comprising side walls and a rear wall, a cooking grate forming the top of said stove, a fuel grate disposed below the cooking grate and positioned to divide the stove into a combustion chamber'above the fuel'grate and air chamber below the same,

movable means carried by some of the walls for supporting the fuel grate,'and a controlling element also carried by one of said walls and disposed exteriorly thereof, said controlling element being connected with'the movable means to actuate the same whereby to effect vertical adjustment of the fuel grate toward and away from the cooking grate, and a vertically adjustable shield at the front of the stove.

In testimony whereofI have aflixed my signature.
